Trying to decide which of these might be more beneficial. It looks like the Explorer pass (historic-scotland.gov.uk/index/…explorer.htm) is less expensive 28 GBP vs 44 for the British pass (britishheritagepass.com/Featured_Properties_…), but the British one says you get free entrance plus "jumping the line" at the attractions. Needless to say, with limited time to sightsee, that would be a bonus. On the Explorer pass site, I don't see where it says you get in free to the venues.
Does anyone know?
